The prevalence of stroke according to indoor radon concentration in South Koreans: Nationwide cross section study
This study combines 2 nationwide studies. Demographic characteristics and medical history of participants were obtained from Korean National Health and Nutrition Examination Survey (KNHANES) from 2007 to 2012. Participants over 40 years old and who completed the questionnaire were included in the study. Indoor radon concentration was analyzed using the mean value of winter housing radon concentration from 2012 to 2016 published by the National Institute of Environmental Research. The average values of each metropolitan city and province were assigned to the residence of the participant. To eliminate the potential confoundi...

Factors affecting in-hospital delay of intravenous thrombolysis for acute ischemic stroke: A retrospective cohort study
This study was designed to investigate the factors affecting the in-hospital delay of intravenous thrombolysis (IVT) for acute ischemic stroke (AIS). Two hundred and forty-eight consecutive AIS patients treated with intravenous administration of alteplase in Gansu Provincial Hospital from December 2014 to August 2018 were enrolled retrospectively in this study. According to door-to-needle (DTN) time, the patients were divided into either a delay group (DTN time> 60 minutes; n = 184) or a non-delay group (DTN time ≤60 minutes; n = 64). The baseline data, laboratory tests, onset-to-door (OTD) time, door-to-acc...

Urban-rural differences in risk factors for ischemic stroke in northern China
This study aims to investigate urban-rural differences in characteristics and risk factors of ischemic stroke in northern China. The present cross-sectional study was based on the High-risk Population Screening and Intervention Project for Stroke. The cluster sampling method was used to select urban and rural screening sites in northern China. By collecting information and screening the data, patients with ischemic stroke were obtained and a control group with similar gender, age, and regional distribution was selected among the nonischemic stroke patients. Then, the demographic and risk factors of patients with ischemic ...
